The concert is called Fare Thee Well: Celebrating 50 Years of Grateful Dead and will take place at Chicago's Soldier Field on July 5. As a press release notes, this concert is taking place almost exactly 20 years after the band's last show with Jerry Garcia.

Band members Mickey Hart, Bill Kreutzmann, Phil Lesh and Bob Weir will all be performing, and they'll be joined by Phish's Trey Anastasio, RatDog's Jeff Chimenti and Grammy-winning artist Bruce Hornsby.

According to a press release, "This will be last time the band will ever play together."

In Canada, Fare Thee Well will be broadcast live in Cineplex theatres. To purchase tickets and see a list of participating theatres, go here.
